Detail
| Problem Description: Updated openswan packages that fix one security issue are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. Description: Openswan is a free implementation of Internet Protocol Security (IPsec) and Internet Key Exchange (IKE). IPsec uses strong cryptography to provide both authentication and encryption services. These services allow you to build secure tunnels through untrusted networks. A NULL pointer dereference flaw was found in the way Openswan's pluto IKE daemon handled certain error conditions. A remote, unauthenticated attacker could send a specially-crafted IKE packet that would crash the pluto daemon. (CVE-2011-3380) Red Hat would like to thank the Openswan project for reporting this issue. Upstream acknowledges Paul Wouters as the original reporter. All users of openswan are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing this update, the ipsec service will be restarted automatically. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 742065 - CVE-2011-3380 openswan: IKE invalid key length allows remote unauthenticated user to crash openswan |
